Numbuh 5

Abigail "Abby" Lincoln (also known as Numbuh 5) is the team spy whose specialty is doing super sneaky work, and aside from Numbuh 1, she may be the only member of the Kids Next Door with any common sense. She appears as one of the main characters in the television series Codename: Kids Next Door. Numbuh 5 is voiced by Cree Summer, who also voiced Chloe Flan from Sabrina: The Animated Series. She would make her first guest appearance in the Danny Phantom crossover Danny Phantom's Adventures of Toy Story 3 and join The Amity Park Adventure Team at the end.
